Example: PPXF SFH inferred from the spectrum presented in Fig. 1b. The 2D weight-grid (shown in Fig.A.1) converted to a mass-weighted SFH, where the ages of the SSP-templates are equivalent to the star formation activity at that look-back time. The SFH is normalized by the total stellar mass of the galaxy M⋆.
